This is what you need....
wrap a thread base on to your hook to about the barb then crush the barb
grab a small piece of chenille or dubbing and "dub the thorax"
these are awesome flies and I tie them from a massive size 2 on a TMC 8089 to a size 12 on a 200r
great for carp, smallies, largemouth, and a variety of panfish I even caught a catfish on one, yup on top!!!
But at any rate
Stay Fly, Be Blessed, See you on the water,
